Abstract

An electrolyzed water production system which regulates the supply amount of strong salt water to be mixed into raw water supplied from a water supply source by feedback control such that the electrolysis current of diluted salt water introduced into an electrolytic bath by mixing the strong salt water supplied from a salt water tank into the raw water has a predetermined current level, where in when the electrolysis conditions of diluted salt water are altered, regulation of the supply amount of strong salt water by feedback control is interrupted temporarily, the supply amount of strong salt water to be mixed into raw water is controlled depending on the alteration factor of the electrolysis conditions, and the supply amount of strong salt water is regulated by feedback control after such a state that the electrolysis current of diluted salt water is maintained at the set current level.
